A phased array ultrasound transducer is typically 2-3 cm long, consisting of 64-128 elements. Phased arrays mean the array arranged in a specific sequence in order to direct the sound wave in a specific direction. A phased array ultrasound probe typically has a smaller footprint than a linear or curved array probe, but can still image a large area. What can you use the Phased Array transducer for? The Phased Array transducer can be applied in Cardiac examinations and Abdominal examinations What is the element of transducers? The element is the most important component of the transducer. It is a thin disc of piezoelectric material near the front surface of the transducer. The crystal material may possess its piezoelectric properties naturally, but more commonly, the piezoelectric properties are artificially induced using a combination of thermal and electrical treatment. What is the principle of ultrasonic transducer? Ultrasound propagates in the human body. Due to the acoustic characteristics of various tissues of the human body, the ultrasonic waves produce reflection, refraction, scattering, diffraction, attenuation at the interface of two different tissues, and the relative movement of the sound source and receiver produces Doppler shift also other physical properties. Receiving the reflected and scattered signal to display various tissue lesions and morphological, then combine the pathology to clinical observation, make the analyze and summarize for the different reflection law also the lesion degree of functional barrier properties then make a diagnosis. This is the working principle of an ultrasonic transducer. What is inside an ultrasound probe? There are sensors, chips, and lithium batteries inside a portable ultrasound transducer. What's the advantage of handheld ultrasound? Advantages of ultrasound probe: Accurate and Instant Diagnoses; Improved Patient Throughput; Affordable Care; A Boon in Emergency Settings; Increased Patient Engagement; Improved Ease of Operation and Convenience; Availability of Many Features and Options. How do you disinfect a ultrasound probe? Step1: Use the Glutaraldehyde solution for disinfection. Step2: The head of the curved ultrasound probe coated with a gel and then cap with a sterile cover, the examination site with saline or sterile cotton ball to wipe can be used to replace disinfection for the sonography probe. Be careful when you disinfect a linear transducer ultrasound. How to do a thyroid examination？ Thyroid ultrasound is a so simple and quick procedure. There is almost without special preparation that you only need to be bare-necked. And due to the medical ultrasonic gel smeared on the mobile ultrasound probe during the examination, you will need to wipe the gel remaining in the overlying skin with some tissues. The convex array transducer is to the benefits of imaging of abdomen, kidney, obstetrics. How should treat or maintain the transducers? Transducers are important and expensive, so you have to caution that: 1.Do not throw, drop, or knock the transducer 2.Don't cover the snowflakes fan(its a cooling fan)on the H/S transducers in use 3.Wipe the gel from the transducer after each use 4.Do not sluice with alcohol-based confections 5.Keep water from the snowflakes fan, it's not waterproof.

An ultrasonic sensor or a probe generates sound waves, and the reflections of the sound waves produce clear images of body tissues and organs, which is an important part of the ultrasound system. The following are the three most common ultrasonic probe types: Linear Probes As the name suggests, there is a linear piezoelectric structure. The beam shape is rectangular, and the near-field resolution is higher than average. Depending on the clinical application, the frequency, footprint, and application of the linear probe are likely to vary. The probe used for 2D imaging has a wide coverage range, and its broadband frequency is 5-20 MHz. It is used to examine the breast, thyroid, tendons and blood vessels, and to measure the thickness of carotid artery disease. Convex ultrasound probe Also commonly called a curved probe, there is a curved piezoelectric crystal arrangement, and the beam is convex. The probe used for 2D imaging has a wide coverage range, and its broadband frequency is about 2.5 MHz-7.5 MHz, which can be used for abdominal and vaginal examinations. The probe used for 3D imaging has a wide field of view, and its broadband frequency is 3.5 MHz-6.5 MHz. 3D bending probes usually use electromechanical moving parts in the head, and are usually used to diagnose pregnancy abnormalities. Phased array ultrasound probe The phased array ultrasound probe is so named because the crystals are arranged in a "stacked" structure. The beam is very narrow, close to a triangle, and the near-field resolution is poor. This kind of probe has a small footprint and a broadband frequency of 2-6 MHz. It is mainly used for cardiac and transcranial examinations. Other types of ultrasound probe Such as the pencil type, intracavity type and transesophageal type, all have a specific purpose: to check blood flow, internal cavity and heart respectively. Some probes, such as laparoscopic probes, are specifically designed for surgical procedures. As a device and solutions provider focused on ultrasound imaging, we aim to make pocket ultrasound machine price affordable for everyone.

There are two methods of classification of transducer and classification according to the marking method of the USG transducer symbols. One is classified by the working principle, and the other is classified by the amount of detection. According to the working principle, there are strain transducers, capacitive transducers, inductive transducers, piezoelectric transducers, magnetoelectric transducers, pyroelectric transducers and photoelectric transducers. In addition to the common classification methods of the USG transducer, there are various classification methods based on transducer material, transducer structure, energy conversion fraction, etc. All of them have their advantages and limitations. 1. The medical USG transducer can be distinguished by detection According to detection, the medical USG transducer can be divided into displacement transducer, flow transducer, temperature transducer, speed transducer, pressure transducer, etc. As for pressure transducers, there are metal strain gauge pressure transducers, semiconductor pressure transducers, capacitive pressure transducers and other USG transducers that can detect pressure. In terms of the temperature transducer, there are thermistors, thermocouples, PN junction temperature transducers and other USG transducers that can detect temperature. 2. The transducer in medical can be classified according to the human senses that can be replaced The USG transducer can be classified according to the human senses that the USG sensor can replace. For example, vision transducers include various optical transducers and other USG transducers that can replace vision functions. Auditory transducers include various pickers, piezoelectric transducers, capacitive transducers, and other USG transducers that can replace auditory functions. Olfactory transducers include various gas-sensitive transducers and other USG transducers that can replace olfactory functions. This classification method is beneficial to the development of bionic transducers. As a professional ultrasound probe manufacturer, We have long been an innovative high-tech enterprise about handheld ultrasound machines featuring the coordinated efforts with the government, enterprises, universities, and research institutions.

1. Introduction of the wireless ultrasound transducer The ultrasonic waves emitted by the wireless ultrasound transducer are also known as mechanical waves, which have good directionality, strong penetrating ability, and the ability to spread in water and air. The wireless ultrasonic transducer can be used for distance measurement, speed measurement, cleaning, welding, stone crushing, sterilization, disinfection, etc. Based on the vibration excitation mode, transducers commonly used in ultrasound can be divided into magnetostrictive transducers and electrostrictive transducers. At the beginning of the 20th century, the development of electronics enabled people to make various electromechanical transducers by using the piezoelectric effect and magnetostrictive effect of certain materials. In 1917, people made sandwich-type ultrasonic transducers with natural piezoelectric quartz and used them to explore submarines on the seabed. With the continuous development of ultrasonic applications in various military and economic sectors, magnetostrictive transducers with greater ultrasonic power have emerged, as well as various types of ultrasonic transducers with different purposes such as electric, electromagnetic, and electrostatic transducers. 2. Application of the wireless ultrasound transducer in medical treatment The application of the wireless ultrasound transducer in medical treatment is mainly divided into medical testing and medical treatment. As you commonly see in hospitals, medical instruments that we can commonly see such as B-ultrasound, color doppler ultrasound, ultrasonic holography technology, ultrasound scalpel, and ultrasound crushing technology all use the wireless ultrasound transducer to work. The working principle of medical ultrasound is similar to that of sonar. When the ultrasonic wave emitted into the human body will be reflected and refracted when they encounter interfaces, and it will be absorbed and attenuated by the human body so that there is no harm to human body tissues. The wireless ultrasound transducer is used in different medical devices with different purposes. Also, the wireless ultrasound transducer is widely used in the medical industry because it is not harmful to the human body. Founded in 2016, Stork takes merely four years to become one of the leading ultrasound probe manufacturers in China. As a device and solutions provider focused on ultrasound imaging, we aim to make handheld ultrasound affordable for everyone.
